The Throat Plate Asm (Part Number: A11153340B0A) is a critical genuine replacement component for Juki and Bernette portable serger/overlock machines. It provides the essential metal surface for fabric support and ensures precise needle alignment for 4-thread overlock stitching. This is usually the failure portion, the remaining Retractable Finger are retrieved from the older Needle Plate.

  • Juki MO Series: MO-334, MO-334DS, MO-634, MO-634D/DE, MO-644D, and MO-654D/DE.
  • Bernette Models: 004, 004D, 006D, 007D, 700D, 800D, 800DL, 1100D, and 1200MDA.

Failure Instances

Common signs that the plate needs replacement include:
  • Needle Strikes: Impacts from bent needles create sharp burrs that snag fabric or break thread.
  • Fabric Ingestion: A worn or enlarged needle hole can cause lightweight fabrics to be pulled down into the feed dogs.
  • Mechanical Wear: Heavy use with dense materials like denim can warp the plate or cause visible scratches that degrade stitch quality.
  • Feed Obstruction: Lint and debris buildup underneath the plate can prevent it from seating correctly, leading to uneven feeding. 

Replacement Procedure

  1. Safety First: Power off and unplug the machine.
  2. Clear Access: Remove the presser foot and needle(s) to avoid obstruction.
  3. Removal: Use a small screwdriver to loosen and remove the two securing screws.
  4. Cleaning: Thoroughly brush away lint from the feed dog area before installing the new part.
  5. Installation: Align the new A11153340B0A plate, ensuring it snaps firmly into position without gaps.
  6. Securing: Reinsert and tighten the screws. Rotate the handwheel manually to verify the needle clears the plate before resuming sewing.
